But we've found that this API become very slow recently, the response timeof one API request is between 15s ~ 25s.

Sometimes the API returns an empty recent change list:[image: SHgNOsVRJPz.png]Other times the length of the response recent change list is always between35~37, even if we set the rclimit parameter to 500.

Hi Wenjie,

Can you please check and let us know if you are still experiencing theproblem?

We have a task https://phabricator.wikimedia.org/T202764 which I suspectdescribes the same issue. It is still open, and even though WDQS isrunning on Kafka in production and thus is not affected by it, I see itevery time I run it on Labs (where Kafka stream is not available). So Ithink the issues with RC API on wikidata are still alive.

There's also a parallel issue ofhttps://phabricator.wikimedia.org/T207718 with RDF fetching, which alsostill happens.
